Machine A Machine B 52 = 49.7 g2 $2 = 33.5 g2 n = 31 n = 31 (a) Is there sufficient evidence to indicate that there is a difference in the precision of the two machines at the 5% level of significance? (Round your answers to two decimal places.) 1-2. Null and alternative hypotheses: Ho: 012 - 322 versus Ha: 012 # 022 O Ho: 012 022 O Ho: 012 - 022 versus Ha: 012 02 3. Test statistic: F = 148 4. Rejection region: F > 5. Conclusion: O Ho is rejected. There is sufficient evidence to indicate a difference in the precision of the two machines. . Ho is not rejected. There is Insufficient evidence to indicate a difference in the precision of the two machines. O Ho is rejected. There is insufficient evidence to indicate a difference in the precision of the two machines. Ho is not rejected. There is sufficient evidence to indicate a difference in the precision of the two machines. (b) Find a 95% confidence interval for the ratio of the two population variances.
